Which of the following is NOT correct about the characteristics of sickle cell anemia?

Choice A reason: Sickle cell anemia is indeed inherited in an autosomal recessive pattern. Individuals must inherit two copies of the mutated beta globin gene (one from each parent) to manifest the disease. Carriers with one copy are typically asymptomatic but may pass the gene to offspring. Choice B reason: The condition results from a point mutation in the beta globin gene, specifically a substitution of valine for glutamic acid at the sixth position. This leads to the production of hemoglobin S, which polymerizes under low oxygen conditions, causing red blood cells to assume a sickle shape. Choice C reason: The sickled red blood cells can obstruct small blood vessels, leading to ischemia and infarction in various tissues, including bones. This can predispose patients to osteomyelitis and bone necrosis, particularly in long bones. Thus, this statement is accurate. Choice D reason: This statement is false and stigmatizing. Patients with sickle cell anemia experience real and often severe pain due to vaso-occlusive crises. Labeling them as drug-seeking undermines their legitimate need for pain management and contributes to healthcare disparities.
